Symplasm is a term often used in plant biology and refers to the interconnected living cytoplasm of cells. Some synonyms for symplasm include plasmodesmata, a term used to describe the channels that connect the cytoplasm of adjacent plant cells, and intercellular channels. Symplastic transport is the movement of molecules through these channels in plants. Another related term is phloem, which is a tissue in plants that transports sugars and other nutrients through the symplasm. Symplastic connections can also play important roles in cell-to-cell communication and signaling. Overall, the term symplasm and its synonyms are important concepts in plant physiology and understanding cellular communication and transport in plants.
